Description

The invention relates to a computer-implemented method for acquiring, transmitting and displaying data of a built-in underground structure. Underground structures such as trenches, utility trenches, or power line trenches are part of the infrastructure and serve to lay cables, pipelines, or drainage systems, for example, during the construction of roads or utility lines. The execution of underground structures must be precisely planned and carried out, as well as comprehensively documented, primarily to facilitate future maintenance of the installed pipes and lines. The construction of underground structures comprises several phases. During the planning phase, the exact positions and dimensions of the structure, particularly a trench, are determined. This involves surveying the subsoil and defining the route. The data obtained in this way serves as planning documentation and the basis for construction. In the construction phase, the excavation of the future underground structure, such as a trench, takes place. Trench shoring or slope stabilization may be used. After excavation, cables, pipelines, or other structural elements are laid in the trench according to the construction plans and in compliance with any applicable installation regulations. Once the lines are laid, the trench is backfilled by adding and compacting a layer of fill material. Finally, the surface of the terrain is restored so that the original and / or intended use of the area (e.g., as a road or green space) can be carried out.Documenting the construction process and progress is a central component of the building process and is carried out both traditionally and increasingly digitally. This documentation serves not only for quality assurance but also as a basis for invoicing, planning and executing connection work, and subsequent maintenance. Traditionally, a construction log is kept to record the progress of the building. Important information such as the materials used, weather conditions, construction progress, and deviations from the plans are recorded manually. Photos and sketches are also used for visualization. However, digital technologies can also be used to document construction progress. Sensors, GPS technology, and 3D laser scanners capture the construction progress in real time, while specialized software solutions visualize the collected data.Digital construction diaries enable the continuous recording and archiving of the construction process. Through the integration of augmented reality (AR) or virtual reality (VR), construction managers can visualize construction progress directly on the construction site. Billing for construction work can be done section by section or based on the entire project, depending on the project structure and contractual agreements. With section by section, construction progress is measured and billed in predefined phases. Alternatively, billing can occur only after completion of the entire project. In both cases, precise surveying and documentation of each construction phase are crucial to ensure transparent billing. The object of the present invention is to create a method by which the construction planning and the documentation of the construction progress and completion can be documented, and at the same time subsequent construction measures can be planned and controlled more quickly and precisely. According to the invention, this problem is solved by the features specified in claims 1, 15 and 18. Preferred embodiments are the subject of the dependent claims. The computer-implemented method according to the invention for controlling the installation of a civil engineering structure or section thereof comprises providing a first data set, comprising image data of an installed civil engineering structure, at least one section of the civil engineering structure installed in the civil engineering structure, and / or at least one component of the civil engineering structure installed in the respective section of the civil engineering structure, as well as position and geometry data of the at least one section of the civil engineering structure installed in the civil engineering structure and / or the at least one component of the civil engineering structure installed in the respective section of the civil engineering structure, in a civil engineering structure database; transferring the data set to a computer unit, wherein the computer unit is preferably granted access to the civil engineering structure database for the transfer; evaluating the data set; and providing the evaluated data set in a mobile, central, and / or decentralized computer unit.based on the evaluated data set, the creation of at least one digital model of the installed underground structure or section thereof and graphical representation of the digital underground structure or section thereof model on a display unit assigned to the computer unit and / or the provision of control data for processing machines for the execution of subsequent installation or maintenance work on the installed underground structure based on the first data set.; A "deep structure" within the meaning of the present invention is a structure built below or near the ground surface and generally serving to develop infrastructure. Deep structures include earthworks and foundation engineering, such as the construction of trenches, foundations, or underground structures. Examples of deep structures are trenches for laying water or power lines, sewers for wastewater disposal, and tunnels for road or rail traffic. The terms “predefined underground structure” or “predefined underground structure section” refer to an underground structure or section that was planned using maps and / or survey data in preparation for the construction project and includes all information for the execution of the construction work, thus representing the target state in the construction execution planning. The terms “installed underground structure” or “installed underground structure section” refer to an underground structure or a section of an underground structure after construction and thus represent the current state after phased or complete construction. The method according to the invention advantageously improves the accuracy of the structural documentation of the installed underground structure and sections thereof, as well as the graphical representation of the installed underground structure and the construction progress. Furthermore, the method allows the provision of control data, which can be used in particular to control processing machines during subsequent installation or maintenance work, in order to connect directly to the already installed underground structure sections.The method according to the invention significantly improves the accuracy of the construction work and allows, even after a longer period of use, for example during later maintenance work, the components of the civil engineering structure to be maintained to be located using the comprehensive documentation and the processing machines to be controlled precisely at the point of use for error-free operation, without the need for costly reconnaissance work on the construction site before construction begins. This is particularly important in cases where the underground structure is covered, for example, by a road or sidewalk surface, and is no longer directly visible. The control data then allows construction machinery to be guided so precisely that it locates the underground structure. Since the geometry and the elements installed within the structure, such as pipes and cables, as well as their location, are known, and additional information / data about the subsoil and backfill material is available, precise control of the execution can be achieved even after extended periods of time or when the subsequent construction project is handed over to other companies. The normally necessary, time-consuming and labor-intensive preliminary investigations, such as new / re-surveying, taking soil samples, detecting pipes, etc., become unnecessary.This can be carried out much more efficiently, as the labor and working time requirements are significantly reduced. The tax data enables the participating contractors and the necessary machinery to execute follow-up and / or maintenance work immediately. Furthermore, the deployment of these machines can be planned more precisely based on the tax data, thereby reducing the effort required to provide them. A further advantageous embodiment of the invention provides that, in the computer-implemented method, the provision of a second data set, comprising planning data of a predefined, to be installed underground structure, at least one predefined section of the underground structure to be installed and / or at least one predefined part of the underground structure to be installed in the respective section, predefined position and geometry data of the to be installed underground structure, at least one section of the underground structure to be installed and / or at least one part of the underground structure to be installed in the respective section, is carried out in the underground structure database, the data of the first data set is assigned to the data of the second data set and the data sets are linked in the underground structure database to create a linking data set;the transfer of the linking data set to a computer unit, wherein the computer unit is preferably granted access to the civil engineering database for the transfer; the evaluation of the linking data set; the provision of the evaluated linking data set in a mobile, central and / or decentralized computer unit;based on the evaluated linking data set, the creation of at least one digital overlay model of the installed civil engineering structure or civil engineering section and the predefined civil engineering structure or civil engineering section to be installed, and the graphical display of the digital overlay model on a display unit assigned to the computer unit, wherein the overlay model can optionally include the graphical display of the predefined civil engineering structure or civil engineering section model to be installed, the installed structure, or a combined digital civil engineering structure or civil engineering section model, and / or the provision of control data for processing machines for carrying out continuation installation or maintenance work on the installed civil engineering structure based on the first and / or the second data set or the linking data set. This allows the data on actually installed structures to be linked with the planning data of the predefined underground structure, enabling a target-actual comparison. This simplifies the precise documentation of construction progress as well as deviations from the original plan, and thus the monitoring and documentation of the underground structure, for example, for subsequent structures and / or later maintenance measures. Furthermore, construction phase- or structure-related billing processes are facilitated and can be carried out with greater precision based on the documented data, since target and actual states can be compared transparently. Furthermore, the use of the control data provided by the method allows for the control of processing machines during ongoing construction work, enabling planned underground structures to be seamlessly and directly connected to already constructed structures, even at a later stage of execution. The method according to the invention significantly improves the accuracy of construction and allows components of the existing underground structure to be located even after a considerable period of time, based on the comprehensive documentation. This enables the processing machines to be precisely positioned and controlled at the work site for error-free operation, without the need for costly reconnaissance work prior to construction, for example, to locate potentially covered structures or to detect pipes and conduits within the structure.The necessary information is contained in the control data and can be implemented and taken into account by the processing machines and construction workers during the work. For example, the starting point for earthworks can be precisely defined using the control data. The immersion depth of an excavator bucket can also be determined to prevent damage to the structure or the pipes and cables laid within it, thus making the construction work significantly safer. The information / data on the subsoil and the backfill material used allows the selection and control of the machinery involved. For instance, if lighter machines are required on less stable subsoil, their selection can be predetermined by the control data.The control of routes on or around the underground structures can also be controlled via the control data in order to guide the construction machinery via the shortest possible and / or safest access to the underground structures. A further advantageous embodiment of the invention provides that the representation of the digital model of the installed underground structure or section and / or the superimposed model additionally includes a graphical representation of the acquired position and geometry data of the installed underground structure or section and / or the predefined position and geometry data of the underground structure to be installed. This advantageously increases the information density and achieves greater transparency in the representation, providing a better basis for subsequent or continuation planning and for controlling the construction measures, the processing machines involved, and the construction workers. Integrating position, location, and geometry information into the digital model(s) enables more precise monitoring and control of the construction process and facilitates a simpler comparison between planned and actual results. Deviations between the construction plans and the actual construction can be quickly identified and displayed in the model, allowing for corrective action during subsequent construction phases. This also simplifies and clarifies the documentation of the civil engineering structure, for example, for future projects and / or maintenance work. A further advantageous embodiment of the invention provides that the position and geometry data, i.e., position, location and / or geometry information of the installed underground structure, section of the underground structure and / or parts thereof, are derived from recorded orthophotos, digital terrain models (DTM), 3D point clouds, textured 3D models (mesh), GPS (Global Positioning System) data points, GIS (Geographic Information System) data points, 2D or 3D measurement data, LiDAR (Light Detection and Ranging) point clouds, aerial or satellite images and / or other survey data. The required information can be acquired using simple means, for example, a suitably equipped mobile phone, in particular a mobile phone or handheld device equipped with a GNSS (Global Navigation Satellite System) module and / or a mobile device with an integrated GPS receiver or LiDAR sensor on the construction site. The captured images or 2D or 3D image data and / or point clouds, as well as GPS / GIS data and associated position data points, can be stored centrally and / or decentrally, for example, in a cloud, and converted into corresponding datasets on-site or in a subsequent step on a computer unit. The datasets can then also be made available in the civil engineering database and linked or used in the method according to the invention. A further advantageous embodiment of the invention can consist in assigning attributes to the data of the installed underground structure in the first data set, wherein the data preferably include the volume of the underground structure and / or underground structure section, the geometry of the underground structure and / or underground structure section, in particular the base width of the underground structure and / or underground structure section, the base length of the underground structure and / or underground structure section, the angle of inclination of the underground structure and / or underground structure section side walls, the distance between the top edge of the underground structure and / or underground structure section and the base of the underground structure and / or underground structure section, the position, length, width, cross-sectional geometry and type of structural elements installed in the underground structure and / or underground structure section, preferably cable or conduit strings, construction planning identification numbers, material properties and / or load properties of a subsoil material and / or a cover material.Material properties and / or load properties of a backfill material, as well as properties relating to the geological layering of the subsoil, are assigned as attributes, and these attributes are assigned to the data, particularly as attribute coding. The digital model of the underground structure or section can then preferably also display the attributes or attribute coding assigned to the data. Assigning these attributes enables a detailed analysis of the structure and materials used, and can serve as a basis for cost calculation and invoicing. Furthermore, it simplifies and refines the central documentation of the completed underground structure, as it not only stores location and geometry information but also provides detailed documentation of the installed elements, the fill material used, and the geological conditions of the subsoil and the installed materials. This documentation is preferably recorded and documented for each individual structure or section. This further simplifies and refines the documentation of the underground structure, for example, for subsequent structures and / or later maintenance measures, and improves the control data for follow-up processing.The ability to display attributes in the digital civil engineering structure or section model simplifies the monitoring of construction progress and increases transparency and precision in the construction steps as well as in the control of structure and construction quality, and improves the data quality of the provided control data. It is advantageous if the method according to the invention further comprises providing positioning means arranged at one or more defined positions relative to the installed underground structure and / or section thereof; detecting the position of the positioning means by at least one detection means; deriving position and geometry data of the installed underground structure by the detection means; and assigning the derived position and geometry data to the data of the first data set, i.e., the detected data of the installed underground structure. The method is advantageously further developed in this context by the fact that the positioning means are designed as physical or digital positioning means, in particular GPS position points, position markers, geodetic positioning means, or virtual positioning means. Recording the positions of the installed underground structure or sections thereof increases the accuracy of the position data in the digital model and simplifies the documentation of the construction work as well as the subsequent invoicing of construction services. The flexibility in the choice of positioning methods allows adaptation to different types of structures and environments, making the application of the method more widely applicable. A further advantageous embodiment of the invention may consist in the mobile computing unit having a mobile visual output device designed as an Extended Reality (XR), Virtual Reality (VR) and / or Augmented Reality (AR) unit, wherein the visual output device is preferably a display, smart glasses, a helmet with a head-up display, a holographic element or a mobile data device, preferably a smartphone or a tablet computer. The advantage of using augmented and virtual reality is that construction managers and engineers can work interactively with and visualize building data directly on-site. This increases efficiency in construction supervision and reduces errors during construction. Documentation of construction progress and execution can also be carried out with greater precision. Compared to a purely two-dimensional plan or map representation, the visualization of the civil engineering structure, construction progress, and final construction can also be improved for clients through the use of augmented and virtual reality. It is advantageous if the method according to the invention further includes: modifying the first data set by inputting modified image data of the installed underground structure, at least one section of the underground structure installed in the underground structure, and / or at least one part of the underground structure installed in the respective section, and / or the recorded position and geometry data of the at least one section of the underground structure installed in the underground structure and / or the at least one part of the underground structure installed in the respective section to input means of the computer unit; providing the modified data in the modified first data set; transferring the modified data set to a computer unit, wherein the computer unit is preferably granted access to the underground structure database for the transfer; and evaluating the modified data set.The provision of the evaluated, modified data set in a mobile, central and / or decentralized computing unit; based on the modified, evaluated data set, the creation of at least one modified digital model of the installed civil engineering structure or section thereof and the graphical representation of the modified digital model and / or the changes in the digital model on a display unit assigned to the computing unit and / or the provision of modified control data for processing machines for the execution of subsequent installation or maintenance work on the installed civil engineering structure based on the modified data set. It is advantageous if the method further includes: assigning the modified data of the first data record to the data of the second data record provided in the civil engineering database and linking the data records in the civil engineering database; transferring the linked data record to a computer unit, whereby the computer unit is preferably granted access to the civil engineering database for the transfer; evaluating the modified linked data record; providing the evaluated modified linked data record in a mobile, central and / or decentralized computer unit; and, based on the evaluated modified linked data record, creating at least one modified digital overlay model of the installed civil engineering structure or civil engineering section and the predefined civil engineering structure or civil engineering section to be installed.the graphical display of the modified digital overlay model on a display unit assigned to the computer unit, wherein the overlay model may optionally include the graphical display of the digital model of the predefined underground structure or underground structure section to be installed, the digital model of the installed underground structure or underground structure section, and / or the modified digital overlay model, and optionally a display of the changes; and / or the provision of modified control data for processing machines for carrying out continuation installation or maintenance work on the installed underground structure based on the modified first and / or second data set or the modified linking data set. The ability to incorporate changes into the model in real time provides flexible and dynamic adaptation to altered construction conditions, significantly simplifying and improving construction project management. Integrating these changes into the civil engineering database ensures seamless documentation and traceability. Furthermore, a planned vs. actual comparison of construction progress can be graphically displayed, and the control of construction machinery can be adjusted accordingly. A further advantageous embodiment of the invention provides that the method further comprises providing an image of the predefined underground structure or section thereof to be installed, based on the data of the second data set, i.e., the data for the predefined underground structure to be installed, on the display unit assigned to the computer unit, and, based on the provided image, a manual or automatic assignment and linking of the recorded data of the installed underground structure or section thereof with the data of the second data set in the underground structure database. The ability to manually or automatically use images to map the actual state of the installed structure to the target state of the predefined structure simplifies construction progress documentation and the verification of recorded data. Furthermore, it increases the accuracy of mapping the data of the installed structure to the data of the predefined structure, and thus also to the provided control data. This mapping can be performed manually using suitable input devices connected to the computer unit, such as digital pens or touchscreens / touchpads. A further advantageous embodiment of the invention may consist in the computer-implemented method according to the invention further comprising the provision of a survey data set of the installed underground structure, comprising a survey area and a survey sketch based on the data of the first data set. In this context, the method further preferably provides the possibility of comparing the survey data set of the installed underground structure with a comparison survey data set provided on the basis of the data of the second data set, i.e., the data of the predefined underground structure, comprising a comparison survey area and a comparison survey sketch; the provision of a comparison survey data set comprising a survey area and survey sketch including red line corrections; and the graphical representation of the comparison survey data set in the digital model of the underground structure or underground structure section. Providing a digital survey dataset can serve to document construction progress and as a basis for calculating construction costs. Integrating an additional survey comparison function enables precise execution and monitoring of construction progress and the early identification of construction errors or deviations from the plans, which can then be addressed in the further course of construction or documented within the project context. It is advantageous if, in a further development, the method according to the invention includes assigning a completion code to the data of the second data set, in particular to the planning data of the at least one predefined section of the underground structure to be installed and / or the at least one predefined part of the underground structure to be installed in the respective section, in order to create a modified linking data set that has already been installed. In this context, the method preferably further comprises providing the data that do not have a completion code; and graphically representing the sections of the underground structure that have and do not have a completion code in the digital model of the underground structure or section. Coding makes it easier to monitor and document the progress of the construction project. Representing this in the civil engineering structure or section model increases transparency in construction execution and simplifies project management, particularly with regard to planning subsequent trades and controlling work processes and the machinery used. Furthermore, completion coding effectively supports both section-by-section and project-by-project billing processes by providing easy access to relevant construction data. An advantageous further development of the method according to the invention comprises selectively determining a work index for the installed underground structure based on the respective installation geometries and / or installation depths of the underground structure; determining a work index for a selection of installed underground structure sections based on the respective installation positions and installation depths and / or the installation geometries of the underground structure sections and / or underground structure parts; or determining a work index for a single underground structure section based on the respective installation positions or installation depths and / or the installation geometries of the underground structure section or one or more underground structure parts of the underground structure section. Data-driven determination of work indicators facilitates the evaluation of construction progress. These indicators also allow for detailed performance monitoring of the participating trades and provide a basis for invoicing the overall project, sections, or sub-trades. This is particularly advantageous when multiple contractors are involved in the construction of the civil engineering structure and simplifies the allocation of completed civil engineering work to individual trades and / or contractors. Work indicators can also be used to document construction progress and to assess the quality and duration of construction work. Especially for follow-up or comparable projects, work indicators can also serve as a planning basis or planning support tool. The invention also encompasses a system for controlling the installation of a civil engineering structure or section thereof, comprising a provisioning unit configured for providing a data set of an installed civil engineering structure, comprising image data of an installed civil engineering structure, at least one section of the civil engineering structure installed in the civil engineering structure, and / or at least one part of the civil engineering structure installed in the respective section of the civil engineering structure, captured position and geometry data of the at least one section of the civil engineering structure installed in the civil engineering structure, and / or of the at least one part of the civil engineering structure installed in the respective section of the civil engineering structure; a transmission unit configured for transferring the data to a computer unit, wherein the computer unit preferably has access to the civil engineering structure database; and an evaluation unit for evaluating the data set.and a conversion unit set up to convert the evaluated data set to provide a digital model of the civil engineering structure or section thereof; and a further provisioning unit set up to provide control data for processing machines to carry out subsequent installation or maintenance work on the installed civil engineering structure based on the data set. It is considered advantageous if the system also has a third provisioning unit for providing at least one civil engineering database, containing at least one data record with planning data for at least one predefined civil engineering structure to be installed, a predefined section of civil engineering structure to be installed, and / or at least one part of the predefined section of civil engineering structure to be installed, as well as position and geometry data of the civil engineering structure to be installed, the predefined section of civil engineering structure to be installed, and / or the predefined part of civil engineering structure to be installed; and an assignment unit for assigning the planning data of the data record of the civil engineering structure to be installed to the recorded data of the data record of the installed civil engineering structure, section of civil engineering structure, or part of civil engineering structure, and for linking the data to a linking data record in a civil engineering database.wherein the transmission unit is configured to transfer the linked data to the computer unit and wherein the computer unit preferably has access to the civil engineering database, and comprising the evaluation unit for evaluating the linked data set and the conversion unit for converting the evaluated linked data set to provide a digital overlay model of the installed civil engineering structure or section thereof and the predefined civil engineering structure or section thereof to be installed, and the further provisioning unit is configured to provide control data for processing machines for carrying out continuation installation or maintenance work on the installed civil engineering structure based on the linking data set. The invention also includes a computer program element with instructions that, when executed on computer equipment in a computer environment, are set up to perform the steps of the computer-implemented method according to the invention in a previously specified system. The invention also encompasses the use of a civil engineering database in the aforementioned method, wherein the civil engineering database contains at least planning data of the predefined, installed, and recorded data of the installed civil engineering structure, civil engineering section, or at least one part of the civil engineering section, and the civil engineering database is configured to identify at least one link between the planning data of the predefined, installed, and recorded data of the installed civil engineering structure and to provide data for converting the data into at least one digital model of the civil engineering structure or civil engineering section in a computer unit and / or for the graphical representation of the digital model on a display unit assigned to the computer unit, and control data for processing machines for carrying out subsequent installation, continuation installation, or maintenance work on the installed civil engineering structure. It should also be noted that terms such as "comprehensive," "exhibiting," or "with" do not exclude other characteristics or steps. Furthermore, terms such as "a" or "that," which indicate a singular number of steps or characteristics, do not exclude a plurality of characteristics or steps—and vice versa. The figures each show preferred embodiments in which individual features of the present invention are combined with one another. Features of an embodiment can also be implemented independently of the other features of the same embodiment and can therefore be readily combined by a person skilled in the art to form further meaningful combinations and subcombinations with features of other embodiments. In the figures, functionally identical elements are provided with the same reference symbols. It shows: Fig. 1 a schematic representation of a combined digital model of a civil engineering structure and sections thereof, according to an embodiment of the invention; Fig. 2 a schematic representation of another combined digital model of a civil engineering structure and sections thereof, according to an embodiment of the invention; Fig. 3 a schematic representation of a digital model of a section thereof, according to an embodiment of the invention; and Fig. 4 a schematic representation of a survey plan and a survey sketch created according to an embodiment of the invention using the acquired and processed data. Fig. 1 shows a schematic representation of a combined digital model 1 of a civil engineering structure 2, 3 or of civil engineering structure sections 4, hereinafter also referred to as a digital civil engineering structure or civil engineering section model 1, according to an embodiment of the invention. For the representation shown, the data provided and linked in the database of the predefined civil engineering structure 2 to be installed and the installed civil engineering structure 3 or the individual installed civil engineering section 4 were converted in a mobile, central and / or decentralized computing unit into digital civil engineering structure or civil engineering section models 1 of the installed civil engineering structure 3 and the predefined civil engineering structure 2 and displayed in combination. Based on the representation, it can be determined whether there are deviations between the predefined, i.e., planned, and installed, i.e.,The data for the underground structure 2, 3, which is recorded on the construction site, are available, thus enabling a target-actual comparison, the results of which are presented graphically and therefore easily comprehensible. Construction progress can also be monitored. The data of the installed underground structure 3 can be recorded on the construction site at time intervals, for example, according to the respective construction phases, or in real time, using suitable mobile and / or stationary data acquisition devices as image data, 3D point clouds, or other survey data. After appropriate transmission to the underground structure database, it is linked with the data of the predefined underground structure 2 stored there and prepared for the graphical representation shown in Fig. 1. Fig. 2 shows a schematic representation of another combined digital model of a civil engineering structure or section 1, i.e., a digital superimposed model according to an embodiment of the invention. Attributes 5 have been additionally assigned to the acquired data of the installed civil engineering structure 3. These can be displayed in the dashboard 6 shown here, i.e., the graphical display and selection interface, as additional information assigned to the graphically represented, installed civil engineering sections 4 and accessible to a user. The assigned attributes 5 increase the information density of the displayed representation and can be used for various analyses. The information can also be stored and used for later analyses or as an information basis for subsequent trades and / or for later maintenance measures on the installed civil engineering structure 3 in conjunction with corresponding control data. Documenting the construction process and progress is a central component of the construction process and is significantly simplified by the inventive method, including the graphical processing of the data. Furthermore, the inventive method enables the control of processing machines for carrying out continuation installation or maintenance work on the installed underground structure based on the first and / or second data set or the linking data set. This is achieved by providing corresponding control data within the inventive method, which allows for automatic and error-reduced or error-free processing even after extended time intervals and of underground structures that may no longer be visible due to being covered over, thanks to the precise and data-based control of the processing machines. The [Figure]The graphical presentation of the data shown in Figure 2 can also be used to quickly inform the site manager or client without requiring their presence on the construction site. The display of the civil engineering structure or civil engineering section model 1 and the additional information can be provided via a decentralized computer, a server, and / or cloud storage and accessed and displayed remotely. Fig. 3 shows a schematic representation of a digital underground structure section model 1 according to an embodiment of the invention. The model depicts an underground structure section 4 designed as a trench 7. Several pipes 8 are laid in the trench 7. For documentation purposes and for deriving operational parameters, the 3D point cloud captured on site, as a graphical representation of the trench 7, was stored in the database along with the recorded position, location, and geometry data of the trench 7. Even after completion of the construction work and backfilling and covering of the trench 7, the information stored for the respective underground structure section can be accessed to enable precise control of processing machines based on the provided control data.This is particularly important when the underground structure 3, designed as trench 7, contains lines 8, such as power, data, or gas lines, which must not be damaged by construction machinery during subsequent construction work or maintenance of trench 7, or when the load-bearing capacity of the construction, backfill, or cover material only permits the use of certain machines. Precise, data-based control of the construction machinery is crucial in this context and contributes to faster, more precise, and safer construction work. A 3D point cloud-generated image of trench 7 or trench section can be displayed, as well as a digital 2D trench profile 9, even if it is no longer visible at the installation site. Trench 7 thus always remains open in the digital representation. Additional information about trench 7 or trench section can be assigned to the respective data as attributes 5 and displayed as information in the civil engineering structure or civil engineering section model 1. Such information includes, for example, the volume and geometry of trench 7, such as the width and length of the trench bottom 10 in civil engineering section 4, the angle of inclination of the trench side walls 11, the distance between the top edge 12 and the trench bottom 10, the geographical position of trench 7 and its cross-sectional geometry, as well as information about the type, dimensions, and location of the installed cable or conduit strings. An attribute can also be assigned to a construction planning or project identification number. As construction progresses, additional section-specific information can be added, such as material properties and / or load properties of the subsoil material 13 and / or a subsequent cover material, material properties and / or load properties of the backfill material installed later, and / or properties for a geological stratification of the subsoil material 13. In addition to displaying the installed trench 7, the data from the trench plan predefined in the construction planning can also be shown, thus enabling a comparison between planned and actual construction. Before, during, and after construction, further views of trench 7 can be captured and displayed as chronological representations, supplemented by additional information assigned as attributes to the respective data of the construction phases.Fig. 4 shows a schematic representation of a survey plan 14 and a survey sketch 15 created according to one embodiment of the invention using the acquired and processed data. Survey plan 14 and survey sketch 15 are digitally created based on a survey data set of the installed substructure 3 derived from the civil engineering data. Additional representation levels, not shown in Fig. 4, can display a comparative survey plan and a comparative survey sketch created based on the civil engineering data of the predefined substructure 2 to be installed, in order to indicate corrections in red. The representations of the digital survey plan 14 and the digital survey sketch 15 shown can be used to document the construction progress and as a basis for calculating the construction costs.Digital creation allows for the continuous recording, presentation, and evaluation of the construction project, as well as the monitoring of construction progress. The comparison of planned and actual data between execution and planning data enables the early identification of construction errors or deviations from the plan, which can then be addressed in the further course of construction or documented and graphically represented within the project context. In addition to the digital as-built plan 14 and the digital as-built sketch 15 created based on the civil engineering data, key performance indicators for the construction project can also be derived from the data and used to assess construction progress. Furthermore, the recorded civil engineering data allows for detailed performance monitoring for the participating trades and provides a digital basis for invoicing the overall project, sections, or sub-trades.The work indicators can also be used to document construction progress and to assess the quality and duration of the construction work, and can be displayed in the representations of the civil engineering structure or civil engineering section model 1 derived from the database (see Fig. 1, Fig. 2 to Fig. 3).
